Kaiser is a Canadian trick-taking card game for four played in partnerships. The game uses a 32-card French-suited deck with a tweaked distribution: AKQJT98 in all suits, plus 7♣, 7♦, 5♥, and 3♠.
Bids are made for how many tricks will be taken, and the winner names the trump suit. Points are added or subtracted depending on whether the bid is made. Each trick is worth a point. Winning the 5♥ or 3♠ is worth +5 or -3, respectively.
The game has been around for at least 40 years and it is believed that it has its origins in the Ukrainian culture, possibly being brought over by immigrants to Canada.
